The Electric double layer capacitor has the main use of a Charge Reservoir. That means a large amount of electrical charge in a small footprint.
These charge/discharge quickly unlike the battery, There is no Electrical Energy to Chemical Energy Transformation and back, like in batteries. It may need caution in design and usage as they may carry a lot of punch.
Also known as Ultracap, Goldcap, Supercap – Electric double layer capacitor, In Farads, like batteries, Energy Reservoirs or eFlywheel.
In Product Safety terms; The Battery has a Internal Resistance, but a Supercap does not. When used in Values like 100F and is fully charged, an Internal or External Breakdown of Insulation or Short Circuit may Occur. The Heat Generated is Enormous. Murphy’s Law says such things happen. Can someone explain more about it to me here at delabs Tweeter. I will echo it in this post. I am not yet conversant about many emerging technologies; i have not put it to practice or built test prototypes.
